摘要： The present invention relates to a digital to analog converter, to a return-to-zero digital to analog converter with improved wideband characteristics by enabling a return-to-zero output without separate clock and controller, and a converting method thereof. Since the return-to-zero digital to analog converter and the converting method thereof are capable of outputting an RZ output without directly providing a clock signal to an analog circuit by configuring a switch for generating a zero point signal and a differential pipeline for providing a differential signal to control the switch according to input digital data using a differential structure, the converter can provide wideband characteristics and high dynamic performance.
